How to install Apache in CentOS 7: Today many servers run on Linux systems for many reasons. Currently, Apache is the most popular web server on the Internet. Lots of active websites are based on Apache web servers. Here, I will show how to install Apache in CentOS 7 or RHEL 7.
The Apache Web Server
It is a server based on HTTP daemon (httpd) which provides simple and secure access to all types of content using either HTTP or HTTPS protocol.
The National Center for Supercomputing Applications (NCSA) developed Apache. Apache is under constant development by the Apache Software Foundation.
RHEL 7 includes Apache 2.4 while RHEL 6 included Apache 2.2. Apache 2.4 comes with the best possible security from the risks.
Apache can be integrated with easily with any software. The most popular stacks are WAMP, LAMP, and XAMPP. This software stacks come with basic integrated components like Apache, MySQL and any of the three scripting languages (PHP, Python, or Perl).
Like any other packages installation, install Apache using yum command. The RPM packages required by the Apache are found in the Web Server package group.
To install Apache, run the following command:
#yum install httpd
However, other additional packages are required as the above command would install only the httpd RPM package. So, to install Apache with other mandatory and packages associated with the Web Server package, use the following command:
#yum install web-server
Now the Apache is installed in your system.
Use the following command to make sure that Apache starts automatically when your system boots next time.
#systemctl enable httpd
Check whether the previous command was successful or not by using the following command:
#systemctl is-enabled httpd
Now start the Apache service with the following command:
#systemctl start httpd
To test whether your Apache server is running successfully or not, after completing the above steps, use your best web browser and enter the following URL.
If your installation is successful, the default testing page would get displayed.
